Curtain wall structure

Abstract

There is described a curtain wall structure in which each glazed element is supported in one point by a compensation bar which is part of the glazed element, which bears on or hangs from a swivel joint projecting from the building skeleton, said element being further retained by members for taking over the forces due to the wind.

I claim: 
     
       1. Curtain wall structure having glazed elements comprised of a metal frame joined to the frontage of a building; a compensation bar supporting each said glazed element in one point on said frame; said compensation bar being part of the glazed element; a swivel joint projecting from the skeleton structure of the building, said compensation bar operatively bearing on or being suspended from said swivel joint; and operatively interengageable members on said elements and building for taking over forces generated due to wind loads acting on said curtain wall structure. 
     
     
       2. Curtain wall structure as claimed in claim 1, said operatively interengageable members for taking over the wind-generated forces each comprising plate members adjustably mounted on said building, said plate members each having a notch formed in the end thereof extending towards said metal frames; and metal sections being provided along the sides of said metal frames and being slidably receivable within the notches of said plate members. 
     
     
       3. Curtain wall structure as claimed in claim 1, comprising connecting pins joining said frame for each said glazed element to the respective metal frame of an overlying or underlying element, said connecting pins including cooperatively engageable male and female portions arranged alternately on the upper and lower ends of said metal frame. 
     
     
       4. Curtain wall structure as claimed in claim 1, comprising a shaped flexible material sealing element joining the metal frames of adjacent glazed elements in both horizontal and vertical directions. 
     
     
       5. Curtain wall structure as claimed in claim 4, said sealing element being in the shape of a cross at the level of the intersection of the vertical and horizontal rows of said glazed elements. 
     
     
       6. Curtain wall structure as claimed in claim 4, said sealing element being V-shaped in transverse cross-section. 
     
     
       7. Curtain wall structure as claimed in claim 4, said sealing element being W-shaped in transverse cross-section.
